By playing in combination with torsional forces through fast descents, bumpy roads, tight corners with too little contact pressure through the quick release it can lead to material removal in and at the dropout, as well as on the chainstays. This should be avoided by a corresponding strong adjustment of the quick release, but also not too tight, so as not to damage the carbon structure by excessive surface pressure again.
If the overall structure is in tact, there are no signs of cracking, so this should not be classified as damage, but further material removal should be avoided in the future.
